实用新型内容
本申请实施例提出了一种投影设备，以解决上述技术问题。
本申请实施例通过以下技术方案来实现上述目的。
本申请实施例提供一种投影设备，投影设备包括壳体和核心模组，壳体包括第一侧盖、前盖、第二侧盖和后盖，第一侧盖、前盖、第二侧盖、后盖和第一侧盖依次相连围合成收容空间，第一侧盖设有进风孔，第二侧盖设有出风孔，第一侧盖与第二侧盖的间距小于前盖与后盖的间距，核心模组设置于收容空间内，核心模组包括光学引擎模块和电子箱模块，电子箱模块下部为中空结构，光学引擎模块部分地设置在电子箱模块的中空结构处。

在一些实施例中，核心模组还包括电源模块，电源模块也设置在电子箱模块的中空结构处，电子箱模块还包括挡板，挡板设置于电源模块与光学引擎模块之间。
在一些实施例中，核心模组还包括红光散热器，红光散热器设置在电子箱模块的下风道处，第一侧盖、散热间隙、红光散热器、第二侧盖共同形成第一散热风道。
在一些实施例中，核心模组还包括绿光散热器，绿光散热器部分地设置在电子箱模块的中空结构处，第一侧盖、绿光散热器、第二侧盖共同形成第二散热风道。
在一些实施例中，核心模组还包括蓝光散热器，第一侧盖、光学引擎模块、蓝光散热器、第二侧盖共同形成第三散热风道。
在一些实施例中，核心模组还包括两个空间光调制装置散热器、色轮模块，两个空间光调制装置散热器和色轮模块均与前盖间隔，两个空间光调制装置散热器层叠设置，第一侧盖、色轮模块、空间光调制装置散热器、第二侧盖共同形成第四散热风道。
在一些实施例中，投影设备还包括外围模组，外围模组分布于核心模组的周边，并相对核心模组独立地设置于收容空间内。

具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
请参阅图1，本申请实施例提供一种投影设备100。投影设备100可以呈 立方体、长方体等结构，本实施例中，投影设备100大体呈长方体结构。投影设备100可以为影院投影机、工程投影机、微型投影机、教育投影机、拼墙投影机、激光电视等。
请参阅图2，投影设备100包括壳体10和核心模组20，核心模组20设置于壳体10内，避免核心模组20直接受到外界的碰撞冲击。
壳体10大体呈长方体结构。壳体10包括第一侧盖11、前盖12、第二侧盖13和后盖14，第一侧盖11、前盖12、第二侧盖13、后盖14和第一侧盖11依次相连围合形成收容空间。
第一侧盖11与第二侧盖13相背，第一侧盖11设有进风孔110，第二侧盖13设有出风孔130，从而有助于壳体10内的热量通过进风孔110和出风孔130散发至壳体10外。进风孔110和出风孔130可以呈圆形、椭圆形、三角形、四边形、其他多边形等形状。进风孔110的数量和出风孔130的数量均为多个，多个进风孔110在第一侧盖11可以排布形成网状结构，多个出风孔130在第二侧盖13可以排布形成网状结构。图2中虚线箭头所指的方向为风流动的方向。
第一侧盖11与第二侧盖13的间距小于前盖12与后盖14的间距，使得壳体10内形成最短路径的风道，有助于提高投影设备100的散热效率。此外，由于风道的路径较短，有效地降低了风在壳体10内而产生的噪音。
第一侧盖11与第二侧盖13的延伸方向可以作为壳体10的长度方向，前盖12与后盖14相背，前盖12与后盖14的延伸方向可以作为壳体10的宽度方向，有助于增加进风孔110在第一侧盖11开设的面积，并且增加出风孔130在第二侧盖13开设的面积，从而增加了壳体10的进风量和出风量以及增加了壳体10内的散热空间，进一步提高了投影设备100的散热效率。
壳体10还包括顶盖15和底盖16，顶盖15和底盖16均与第一侧盖11、前盖12、第二侧盖13和后盖14连接。在投影设备100处于正常使用状态下，底盖16可以朝向地面方向，顶盖15可以朝向空中方向。
请结合图2和图3，核心模组20位于收容空间内。核心模组20包括光 学引擎模块21和电子箱模块22。光学引擎模块21和电子箱模块22可以依次自前盖12朝后盖14的方向间隔排布，有助于光学引擎模块21和电子箱模块22形成的散热间隙迎合进风孔110和出风孔130形成的风道，提高光学引擎模块21和电子箱模块22的散热效果。图3中虚线箭头所指的方向为风流动的方向。
电子箱模块22大体呈阶梯状。电子箱模块22下部为中空结构，或者说，电子箱模块22的朝向底盖16的方向与底盖16形成间隔空间，光学引擎模块21部分地设置在电子箱模块22的中空结构处或间隔空间处，有助于减少光学引擎模块21和电子箱模块22占据壳体10在前盖12和后盖14之间的空间位置，有助于提高壳体的空间利用率。
本申请提供的投影设备100在第一侧盖11和第二侧盖13分别开设进风孔110和出风孔130，由于第一侧盖11与第二侧盖13的间距小于前盖12与后盖14的间距，有助于投影设备100形成最短路径的风道，提高投影设备100的散热效率。此外，由于光学引擎模块21部分地设置在电子箱模块22的中空结构处，光学引擎模块21和电子箱模块22之间的位置排布得较为合理且有助于减少占据壳体10的空间位置，在不影响投影设备100的散热的情况下，有助于提高壳体10的空间利用率，促进投影设备100的小型化。
在一些实施例中，请参阅图2和图3，投影设备100还包括电路板23，电路板23用于协调各模组和模块的功能，保证投影设备100的正常工作。电路板23设有输入接口、耳机接口、音频接口、USB接口、内存卡接口等接口结构以丰富电路板的功能。
请结合图4，电路板23的数量为多块，例如两块或三块或四块或五块，本实施例中，电路板23为两块，两块电路板23依次自底盖16朝顶盖15的方向间隔设置于电子箱模块22。其中一块电路板23与电子箱模块22的顶板220形成另一个散热间隙91，另一块电路板23与电子箱模块22的中板221形成另一个散热间隙91，并且两块电路板23之间又形成另一散热间隙91，本实施例通过将多块电路板23在电子箱模块22内自底盖16朝顶盖15的方 向上进行合理地排布，充分利用电子箱模块22的高度方向的空间位置，有助于减少占用壳体10内的其他空间，提高壳体10的空间利用率，减小投影设备100整机自第一侧盖11朝第二侧盖13方向的外形尺寸以及前盖12朝后盖14方向的外形尺寸，促进投影设备100的小型化。图4中虚线箭头所指的方向为风流动的方向。
在一些实施例中，请参阅图2，投影设备100还包括外围模组80，外围模组80设置于收容空间内。外围模组80分布于核心模组20的周边，外围模组80相对核心模组20独立地设置于收容空间。本申请实施例的投影设备100通过将外围模组80分布于核心模组20的周边，使得外围模块和核心模组20之间的位置排布得较为合理，由于外围模组80相对核心模组20独立，外围模组80的安装和拆卸不影响核心模组20，方便设备维护。
在一些实施例中，请结合图2和图3，外围模组80和核心模组20之间设有散热空隙90。外围模组80可以包括防尘模组30、风扇模组40和镜头模组50，外围模组80中的每个模组均可以与核心模组20形成相应的散热空隙90以提高投影设备100的散热效率。
在一些实施例中，请参阅图2，防尘模组30与核心模组20间隔排布，散热空隙90形成于防尘模组30与核心模组20之间，助于外界冷风经防尘模组30进入壳体10内后直接吹向核心模组20。防尘模组30呈网状结构，防尘模组30用于粘附空气中的杂质尘埃。防尘模组30可以设置于第一侧盖11与核心模组20之间，例如防尘模组30可拆卸地安装于第一侧盖11的朝向核心模组20的表面，有效地减少含有较多杂质尘埃的空气进入壳体10内，避免了该杂质尘埃覆盖在其他模组的表面而影响散热。
在一些实施例中，请参阅图2，核心模组20与风扇模组40间隔排布，散热空隙90形成于风扇模组40与核心模组20之间。风扇模组40可以由多个小风扇规则地排布形成，风扇模组40用于将壳体10内的空气运输至壳体10外，风扇模组40可以设置于第二侧盖13与核心模组20之间，例如风扇模组40可拆卸地安装于第二侧盖13的朝向核心模组20的表面，有助于风扇 模组40将核心模组20产生的热量直接运输至壳体10外，加快了提高壳体10内的热量散发至外界的效率。
在一些实施例中，请参阅图2，镜头模组50与核心模组20间隔排布，散热空隙90形成于镜头模组50与核心模组20之间。镜头模组50大体呈筒状结构，镜头模组50用于将影像投射至壳体10外，镜头模组50可以设置于靠近前盖12与核心模组20之间，例如镜头模组50的两端可以分别承托于前盖12与核心模组20，避免了占用第一侧盖11和第二侧盖13的过多位置，对壳体10的进风量和出风量的影响较小，使得镜头模组50在壳体10内的排布位置较为合理。
在一些实施例中，请参阅图2和图3，核心模组20还包括电源模块60，电源模块60安装于电子箱模块22内并自电子箱模块22的朝向后盖14一侧外露于电子箱模块22。电源模块60用于为其他模组和模块提供电力。由于电源模块60位于电子箱模块22的中空结构处，电源模块60和电子箱模块22之间的排布位置有助于减少占据壳体10的空间位置，有助于提高壳体10的空间利用率，促进投影设备100的小型化。
请参阅图4，电子箱模块22还包括挡板222，挡板222设置于电源模块60与光学引擎模块21之间。在将电源模块60安装于电子箱模块22的过程中，挡板222有助于限定电源模组60的安装位置，避免工人将电源模块60安装过度而使得电源模块60与光学引擎模块21的间距过小而不利于电源模块60和光学引擎模块21的散热。
在一些实施例中，请参阅图2，防尘模组30、核心模组20和风扇模组40依次自第一侧盖11朝第二侧盖13的方向排布于壳体10内，镜头模组50和电源模块60依次自前盖12朝后盖14的方向排布于壳体10内，使得各模组之间的位置排布得较为合理，在不影响各模组的散热的情况下，有助于提高壳体10的空间利用率，促进投影设备100的小型化。
在一些实施例中，请参阅图2，第一侧盖11、前盖12、第二侧盖13和后盖14之间拆卸地连接，即第一侧盖11可以单独地从壳体10上拆卸下来， 前盖12也可以单独地从壳体10上拆卸下来，第二侧盖13也可以单独地从壳体10上拆卸下来，后盖14也可以单独地从壳体10上拆卸下来，从而有助于投影设备100的维修。侧盖之间的连接方式可以采用螺纹连接方式，也可以采用卡扣连接方式。在工作人员需要清理防尘模组30的灰尘的情况下，工作人员可直接将第一侧盖11拆卸下对理防尘模组30进行清理而不需要将整个壳体10都拆开。同样地，工作人员将前盖12拆开可对镜头模组50进行检测维修，将第二侧盖13拆开可对风扇模组40进行检测维修，将后盖14拆开可对电源模块60进行检测维修。
在一些实施例中，请参阅图3和图4，核心模组20还包括红光散热器24，红光散热器24设置在电子箱模块22的下风道处，第一侧盖11、散热间隙91、红光散热器24、第二侧盖13共同形成第一散热风道92。红光散热器24为散热鳍片结构。红光散热器24可以位于电源模块60与风扇模组40之间。由于红光散热器24产生的热量较多，若将红光散热器24设置于进风孔110位置处，则会导致外界的风吹至红光散热器24时将携带红光散热器24的热量吹至壳体10内的其他位置，不利于壳体10内的其他模组的散热。本实施例通过将红光散热器24设置于电子箱模块22的下风道处，即将红光散热器24设置于电子箱模块22和风扇模组40之间，有助于风扇模组40将红光散热器24产生的热量及时地运输至壳体10外。此外，由于电源模块60沿第一侧盖11朝第二侧盖13的方向的长度小于第一侧盖11与第二侧盖13的间距，将红光散热器24设置于电源模块60与第二侧盖13之间的间隔空间中不仅有利于壳体10为红光散热器24提供独立的散热风道以增强散热效果，还有利于充分利用壳体10内的空间位置，提高壳体10的空间利用率，促进投影设备100的小型化。图3中虚线箭头所指的方向为风流动的方向。
在一些实施例中，请参阅图4，核心模组20包括光学引擎模块21，光学引擎模块21和电子箱模块22依次自前盖12朝后盖14的方向排布。光学引擎模块21与镜头模组50连接，光学引擎模块21位于镜头模组50与电子箱模块22之间，光学引擎模块21用于发出光线，光线经由镜头模组50射出至 投影设备100外。光学引擎模块21可以部分地伸入电子箱模块22内，从而减小了光学引擎模块21和电子箱模块22占据壳体10的自前盖12朝后盖14的方向的空间，有助于提高壳体10的空间利用率。
在一些实施例中，请参阅图5，核心模组20还包括绿光散热器25，绿光散热器25部分地设置在电子箱模块22的中空结构处，第一侧盖11、绿光散热器25和第二侧盖13共同形成第二散热风道93，有助于壳体10通过该第二散热风道93同时为绿光散热器25和电子箱模块22进行散热，提高投影设备100的散热效率。此外，绿光散热器25为散热鳍片结构，绿光散热器25设置于光学引擎模块21与第一侧盖11形成的间隔空间中，有助于充分利用壳体10内的空间位置，提高壳体10的空间利用率。图5中虚线箭头所指的方向为风流动的方向。
在一些实施例中，请参阅图6，核心模组20还包括蓝光散热器70，第一侧盖11、光学引擎模块21、蓝光散热器70和第二侧盖13共同形成第三散热风道94，有助于壳体10通过该第三散热风道同时为蓝光散热器70和光学引擎模块21进行散热，提高了投影设备100的散热效率。此外，蓝光散热器70为散热鳍片结构。蓝光散热器70可以设置于光学引擎模块21与第二侧盖13形成的间隔空间中，有助于充分利用壳体10内的空间位置，提高壳体10的空间利用率。图6中虚线箭头所指的方向为风流动的方向。
在一些实施例中，请参阅图5，核心模组20还包括色轮散热器26，色轮散热器26为散热鳍片结构。色轮散热器26位于位于第一侧盖11与前盖12的连接处，本实施例通过将色轮散热器26设置于壳体10的角落位置，并且由于色轮散热器26近似呈规则的长方体状外形，使得色轮散热器26与该角落位置更加相适配，有助于充分利用壳体10内的空间位置，提高壳体10的空间利用率。
在一些实施例中，请参阅图4和图5，色轮散热器26、蓝光散热器70和红光散热器24依次自前盖12朝后盖14的方向间隔排布并两两之间形成散热风道，有助于壳体10通过该散热风道同时为色轮散热器26、蓝光散热器 70和红光散热器24进行散热，提高投影设备100的散热效率。
在一些实施例中，请参阅图6，核心模组20还包括色轮模块(图未示)和两个空间光调制装置散热器，两个空间光调制装置散热器可以分别为红光数字微镜装置散热器28和蓝绿光数字微镜装置散热器29，两者均为散热鳍片结构。图6中虚线箭头所指的方向为风流动的方向。
两个空间光调制装置散热器和色轮模块均与前盖12间隔，两个空间光调制装置散热器层叠设置，例如红光数字微镜装置散热器28和蓝绿光数字微镜装置散热器29可以依次自底盖16朝顶盖15的方向间隔设置，充分利用投影设备100的高度方向的空间位置，有助于进一步提高壳体10的空间利用率，减小投影设备100整机自第一侧盖11朝前盖12方向的外形尺寸，促进投影设备100的小型化。
第一侧盖11、色轮模块、空间光调制装置散热器、第二侧盖13共同形成第四散热风道。由于色轮散热器26位于红光数字微镜装置散热器28的上风位置，风经色轮散热器26吹出后吹向红光数字微镜装置散热器28，如图6所示的第四散热风道95；并且经色轮散热器26的鳍片吹出后形成的风的风压增大，在该增大风压后的风吹向红光数字微镜装置散热器28后，有一部分的风自底盖16朝顶盖15的方向吹向蓝绿光数字微镜装置散热器29，如图3所示的第四散热风道95，有助于提高红光数字微镜装置散热器28和蓝绿光数字微镜装置散热器29的散热效果。
两个空间光调制装置散热器位于第二侧盖13与前盖12的相连处，由于两个空间光调制装置散热器均近似呈规则的立方体状外形且设置于壳体10的角落位置，使得两个空间光调制装置散热器与该角落位置更加相适配，有助于充分利用壳体10内的空间位置，提高壳体10的空间利用率。
在一些实施例中，请参阅图7和图8，核心模组20还包括前挡板27，镜头模组50穿设前挡板27，前挡板27分别与色轮散热器26、蓝绿光数字微镜装置散热器29间隔并形成第五散热风道97，有助于壳体10通过第五散热风道97同时为色轮散热器26、红光数字微镜装置散热器28和蓝绿光数字微镜 装置散热器29进行散热，提高投影设备100的散热效率。图7和图8中虚线箭头所指的方向为风流动的方向。
